§ Mr. DismoreTo ask the Secretary of State for the Environment, Transport and the Regions what are the present air quality standards in the vicinity of Brent Cross shopping centre, with reference to(a) carbon monoxide, (b) nitrogen oxide, (c) nitrogen dioxide and (d) particulate material below 10 microns; what are the pertinent European limits for (a) to (d); and if he will make a statement. [9185]
§ Angela EagleAs part of its national air quality monitoring programme, my Department, in collaboration with local authorities, monitors air pollutants using automatic and non automatic methods across London. The two automatic monitoring stations closest to the Brent Cross shopping centre are (i) an urban background station in the Kingsbury area of the London boroughs of Brent and (ii) a roadside station situated next to the A41 Great North Way at Swiss Cottage, in the London borough of Camden. The results of this monitoring for carbon monoxide, nitrogen oxide, nitrogen dioxide and particulate material below 10 microns, measured during 1996, are presented in the Table below.
Site Carbon monoxide—max 8 hour running mean Nitrogen oxide—98th percentile of hourly means Nitrogen oxide—98th percentile of hourly means Particles (PM10) max 24 hour average Brent 8.00 ppm 191 ppb 55 ppb 61 ug/m3 Camden Not measured 397 ppb 57 ppb 77 ug/m3 My Department also monitors nitrogen dioxide using non-automatic methods, in collaboration with local authorities, in its national diffusion tube survey. The results from the sites nearest to the shopping centre, for 1995, are given in the table.
